Correcting when child is sick

Hi Nicholeen! I was just curious as to how you suggest we correct behaviors when a child is sick? My ten years old daughter has been sick the last few days, and she can get pretty grouchy during this time. She also hasn't had much energy so I've been hesitant to have her do a chore when misbehaving. I have been trying to bring to her attention things that she's doing that aren't respectful, like an annoyed/mean tone in her voice when speaking to us and what to do instead, but that's all I've done so far.
